UNITED STATES JOHN H. FELldLEE, OF DENVER, COLORADO.

DEVICE FOR LOADING AND UNLOADING.

SPECIFICATION forming part of Letters Patent. No. 307,107, dated October 28, I884.

Application filed June 16, 1884. (No model.)

To all whom, it may concern:

Be it known that I, JOHN H. FELMLEE, a citizen of the United States, residing at Denver, in the county of Arapahoe and State of Colorado, have invented certain new and useful Improvements in Devices for Loading and Unloading Ore, Coal, and other Articles, of

which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to apparatus for loading and unloading ore, coal, and other articles; and it consists in certain improvements in the construction of such apparatus, as hereinafter described and claimed. 7

I11 my construction an endless cable is provided, which passes over wheels of peculiar construction, and has horizontal bars or rods secured centrally to the cable. To each of said bars two carrying-buckets are attached, which are carried forward from the point where they are filled to the terminal or dumping end of the apparatus, and, coming in contact with a dumping device, are emptied,

and then returned to be again filled. The coal or article to be loaded is passed down inclined chutes, and falls into receiving-boxes suspended to scale-beams for weighing the contents. XVhen said boxes have received certain quantities in weight they are automatically tilted and discharge their contents into the buckets, and are then returned to their first positions. XVhen the buckets arrive at the terminal or discharge point they are antomatically dumped, and then carried back to the receiving-boxes to be again filled. An adjustable shaftis also provided for communicating power to the apparatus, when desired. Provision is also made for governing movement, and also for rendering the cable steady in passage and preventing its slipping. Intermediate supporting devices are also provided.

Referring to the drawings, Figure 1 is a sectional side view illustrating the loading portion of my improved apparatus. Fig. 2 is a partial plan of the same. Fig. 3 is a sectional side view of the unloading or terminal part of the apparatus. Fig. 4 is a front view of a tower supporting the cable intermediately. Fig. 5 is a side view of same. Fig. 6 represents, in side and sectional edge views, one

of the wheels used to support the cable intermediately. Fig. 7 represents, in front and side views, a gripping device for the cable, which is applied to one of the wheels over which the cable passes. Fig. 8 represents a governing device applied to the terminal wheel.

A designates the frame-work which sup ports the loading devices, and B the inclined chutes, down which the article to beloaded passes to the receiving-boxes 0. Each of said boxes is suspended by means of rods a to a scale-beam, D, having its pivotal attachment at c for weighing the contents of boxes. The rods a are connected with the ends of the cleats or cross-pieces d, one being fastened to the bottom of each receiving-box near the rear end thereof. Each box C, when in position to receive the ore or coal from a chute, B, is held between two of the fixed horizontal pieces E, fastened to cross-beams F, with the cleats'd extending into recesses or notches c in the lower. sides of the fixed pieces E. The front end of each box is left open, and is hinged to the forward ends of the pieces f, the

rear ends of which are hinged to a cross-beam,

G, for the purpose hereinafter stated.-

H indicates a vertical frame placed in front of and near the boxes G, and suspended by chains passing over pulleys g and provided with weights g".

I indicates a bar, hinged at its rear end to a cross-beam, F, and extending forward between the boxes 0 and through frame H, the forward part of said bar resting on a crossrod or pin, h, fixed in said frame. The free end of bar I is provided with prongs t, for connection with horizontal rods to which the carryingbuckets are hung, as hereinafter stated.

At the loading end of the apparatus the endless cable M, which carries the buckets, passes over a wheel, J, and from thence downward to and abouta lower wheel, J, bringing the cable for a short distance on a vertical line, as shown. To the cable M is secured a number of bars or horizontal rods, is, the same being secured centrally to the cable at suitable distances from each other, and two carrying-buckets, K, are hung to each of said bars, one being at either side of the cable. To the sides of each of the wheels J and J are pivotally secured the star-wheels m, the same being constructed substantially as shown, with connection between said shaft and wheel l\' points and concave edges between them; and said star-wheels are so arranged along the pc riphcries of the wheels J J that the points project beyond the peripheries of said wheels. The star-wheels m are rotated independently by contact with bars 7.', carrying the buckets. They serve as flanges to the wheels, to which they are pivoted, keeping the cable in place 011 said wheels, and as the bars L come in contact with them they are partially rotated and allow the bars to bear against the peripheries of Wheels J and J.

The scalebeam having its weights set to weigh a certain quantity-say twenty five pounds-when that quantity has been poured into box (I the box sinks, taking the cleat d from the notches c, and swings forward, its movement being governed. by the hinged bars f, to which the front end of the box is hinged.

This movement brings the front ends of bars f and the box to rest on a cross-bar, b, of the frame H. The cable M at the same time pass ing over wheel J in the direction indicated by.

the arrow .49 in Fig. 1, and a bar, 7;, descending with two buckets, the said bar catches the prongs i of hinged bar I, said prongs straddling the cable, and said bar I, and consequently frame H, are pressed downward, the boxes 0 being thus tilted forward, as indicated in dotted lines in Fig. 1, discharging their contents into the buckets, which have meantime reached the proper position below. \Vhcn the pronged end of bar 1 is brought down to a certain point, it slips from bucket-carrying bar It, and the frame His immediatelyraised by the'weights g, bringing upward bar I and boxes 0 and returning them to their first positions.

L indicates a fixed cross piece under and a suitable distance below the scale-beam to. form a stop to prevent it from being drawn down too far by the operation of box 0.

If, during the passage of the cable, the boxes 0 are not loaded suliieiently to cause their de scent and forward movement, as above described, the bar 7.:, descending, catches the pronged bar I, but only brings it downward a short distance and releases it, when, by the operation of frame If, it is raised to its first po sition.

At the terminal or discharge end of the apparatus is a terminal wheel, N, the cable M passing about said wheel in the direction indicated by the arrows in Fig. 3. The wheel. N is mounted in a frame, 0, which is a slid ing frame, and is provided with a weight, 1', at the end of a cord passing over a pulley, 1-, and attached to the frame, the weight serving to keep the cable extended and tightened.

\Vhen the cable is adjusted in position at a suitable inclination, it operates automatically, the weight of the loaded buckets descending being sufficient to return the empty buckets to the loading end, but when it is desired to communicate power to drive the mechanism, this may be done by means of an adjustable shaft, Q, in suitable bearings on the frame,

being readily effected through gearing R. The said shaft Q, being adjustable in length, is usually constructed with a joint, one sec tion of the shaft entering a hollow portion of another section, and being secured by one or more fixed pins extending into slots.

The gripping devices illustrated in Fig. 7

may be secured to the terminal wheel N or to a suitable intermediate wheel. Each gripping device has the jaws 1?, which are pivotally attached to the wheel on opposite sides at 12., near the periphery. To the shanks or lower ends are fastened the springs 0, which are also severally fastened to the wheel, as indicated by p. The wheel is recessed at q to receive the lower ends when pressed inward by the springs, and is also recessed somewhat at the periphery to allow the jaws to partly sink therein, as seen in Fig. '7. The springs ohold the jaws lopen until the cable M, pressing between said jaws, brings them together, thus binding the cable and preventing its slipping, so that its/movement is steady and uniform.

A governing device is provided for the mechanism, and is applied to any suitable whcelusually the terminal wheelas seen in Fig. 8. Said device has two airumps, S, with their piston-rods connected with a pivotcd lever, T, which is connected with the wheel by connecting-rod s and a crank-pin, the pistons making alternate strokes as the wheel revolves.

At the discharge end of the apparatus is placed a chute, U, down which the carryingbuckets discharge their contents. To the upper end of the chute is hinged a dump-board, I, which is so constructed and attached that it is held in a vertical position, extending upward beyond the plane of the chute, as indicated in dotted lines in Fig. 2). \Vhena pair of loaded buckets is brought in contact with the dump-board l, the moving cable carrying the bucket, brings them, and also the board t, to inclined positions, the forward end of the board lapping on the chute, as shown in the drawings. The buckets being thus emptied and carried forward, the dump-board resumes its vertical position.

For supporting the cable at one or more points along the same a tower is placed, the same being constructed of frame-work V, and provided with two wheels properly guarded and mounted, one above another, in positions to support the upper and lower parts of the end less cable. Each of said wheels is a triple wheel, being composed of three parts on the same shaft or be] t, each part beingindcpendent in movement. (See Fig. (5.) The central part, uv, is a plain wheel, 011 which the cable bears, and the side wheels, 1*, are indented or provided with pointsa, extending beyond the periphery of wheel '10, serving as flanges for said wheel and retaining the cable in position thereon. Vhen a bar, 7;, carrying buckets, comes in contact with the indented peripheries of wheels 1; it is allowed to close against the periphery of wheel 10. One of these triple wheels maybe placed at any desired point to support the cable, which may be made round, in section, or of any suitable form.
